They are completely different. Miyoshi focused more on expensive over the top ingredients & theatrical effect while Jo offered more variety of dishes showing the culinary skill of the chef, in additional to ingredient sourcing skill. Jo is a smaller restaurant with wooden counter. It’s a simple yet elegant restaurant so the vibe at both places is completely different too. By the way, there’s one gentleman in their board wrote his comment on Miyoshi on this board too.
@Chayo You will need a Japanese to make reservations and go along with you. Saito-san is not running a travel agency. Does not seem ethically right for you to request Saito-san to arrange a Japanese speaker to go with you. Just my two cents worth.
Sorry for the late reply but I think that they only accept reservations via facebook from Japanese customers . I actually gave the contact of one of my friends in Japan instead of my own information. (+ I wrote to them in Japanese). They must've thought I was Japanese haha. Maybe next time you should try that instead.
Dons de la nature is said to be a quality restaurant, but when I ate there before, the steak had several grilling issues that seemed to have been caused by insufficient technique by the chef.
If you are planning to go to either one of the two now, I would recommend vesta.
